Topic: Wallets & Exchanges (Read 119 times)

I've just started in the mining world here and have been having a really hard time making a decision on a wallet to use; external, physical drive like Trezor or online wallet like Copay, Electrum, & Mycelium.  I have been reading non stop for a week and still don't feel confident in the decision I'd be making.  Probably because the truth about the whole security thing and not getting scammed is, if it is on the internet it CAN be hacked.  I know "internet safety" is one of the most oxymoronic phrases ever cooked up by anyone, and every time I watch a video of Zuckerberg on webcam with someone and I see the monitor BEHIND him with a post it over his monitor webcam, I chuckle because not even billionaires can admit that there is such a thing as "safe" on their machines.  They know better.  That has been part of my problem.  KeepKey and Trezor seem ideal for that exact problem, and they are compatible with a number of coin wallets and exchanges, but I also know dang well, those can be stolen, physically stolen and you're screwed anyhow.  Then you're into the paranoid back up of your back up crap already and it just isn't worth it.

So, in people's seasoned, learned opinions, what coin wallets do you trust? 
What exchange do you trust?
(I've heard people sing the praises of CoinBase more than anyone else.  I had an account with them, but when I tried to put 0.46+ ETH into my ETH wallet on there...NO dice.  Left my mining device, never made it into the account.  I was told that it was because I was "using an exchange like a wallet, and you can't do that.", but no one has ever said that in ANY tech and crypto articles that I've read.)

Also, I follow the market up and down on the daily and there are LiteCoin apps popping up all over the place but...they are like mining for PESO compared to the other crypto currencies out there like BTC and ETH.  Is anyone really getting serious about LTC, or is everyone just mining EVERYTHING "just in case"? 
My people tell me to just get everything but...when you don't have a wallet and an exchange, that seems stupid to do.

Is CoinBase really the best exchange for all currencies or are there others I should consider? 
I went with them because they DO take BTC, LTC, ETH, BTH (bitcoin cash), and one other currency as of a couple days ago.  Are there other exchanges that are that diversified in their currencies?

What coin wallet for PC or mobile/tablet devices is the one that you trust without second guessing yourself?

Do you recommend INVESTING in the currencies on the market or just mining, or BOTH?

I'm new to all of this but the questions came up pretty quickly.  I don't want to waste my time mining like a fiend like I have been if there is no way to keep it safe and in the end I break even or...end up spending a crapton of REAL money to keep the imaginary money safe.

Thanks in advance for the advice!  I appreciate it!
